After Burst for Game Boy was released exclusively in Japan by NCS in 1990. Conceptually just a simple 2D shooter, it has three modes: Normal, 1P VS, and 2P VS.

The game features a ballistic bullet mechanic where you can charge each shot to have a higher exit velocity. Since only one player bullet can be visible at a time, the damage that can be done in any given timespan is severely limited, necessitating hitting multiple targets in one shot for best efficiency. Quite strikingly, this game is plagued by extreme lag, slowing in-game time down significantly.

This run completes the Normal mode's 30 stages in record time. We also have a run of the 1P VS mode, which has different stages.
